P3602ABRP Equivalent & Substitute Parts

Part Overview

The P3602ABRP is a SIDACtor® thyristor transient voltage suppressor manufactured by Littelfuse Inc., designed for 170V/340V off-state voltage applications with 250A peak pulse current capability in a 3-SIP TO-220 Modified package. This part is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement continuity. Active alternatives with identical electrical and mechanical specifications are available to maintain circuit performance while ensuring supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P3602ABRP is determined by strict equivalence across all electrical parameters and mechanical form factor. The allowed substitution criteria are:

• Identical voltage ratings: Breakover (220V, 440V) and off-state (170V, 340V)
• Identical current specifications: Peak pulse (8/20µs) at 250A and (10/1000µs) at 80A
• Identical on-state voltage: 4V
• Identical hold current: 150 mA
• Identical element count: 2 elements
• Identical capacitance range: 50pF, 90pF
• Identical package and mounting: 3-SIP, TO-220 Modified, through-hole
• Same manufacturer series: SIDACtor®

The substitute parts P3602ABL and P3602ABLRP meet all these criteria. Differences between these parts are limited to packaging format (bulk versus tape & reel) and product status (active versus obsolete), which do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both P3602ABL and P3602ABLRP are direct functional equivalents to the obsolete P3602ABRP. Selection between these two active alternatives depends on procurement and assembly requirements:

P3602ABL is supplied in bulk packaging and is suitable for applications where components are manually placed or processed through non-automated assembly lines. This option provides cost efficiency for lower-volume production runs.

P3602ABLRP is supplied in tape & reel format and is optimized for automated pick-and-place assembly processes. This packaging format reduces handling time and improves assembly throughput for high-volume manufacturing.

Both substitute parts carry ROHS3 compliance and REACH unaffected status, providing regulatory advantages over the original obsolete part. Inventory availability is comparable for both options, with P3602ABL at 1076 pieces and P3602ABLRP at 1004 pieces in stock.

Frequently Asked Questions (FAQ)

Q: Can P3602ABL and P3602ABLRP be used interchangeably with P3602ABRP?

A: Yes. All three parts are electrically and mechanically identical across all specified parameters. The only differences are packaging format and product status. Circuit performance and PCB footprint compatibility are identical.

Q: What is the difference between bulk and tape & reel packaging?

A: Bulk packaging (P3602ABL) supplies components loose in a container, suitable for manual assembly or low-volume processes. Tape & reel packaging (P3602ABLRP) supplies components on continuous tape in reels, optimized for automated assembly equipment. Both contain the same component.

Q: Why is the original P3602ABRP marked as obsolete?

A: Obsolescence indicates the manufacturer has discontinued production of this specific part number. However, active equivalents with identical specifications remain available from the same manufacturer, ensuring design continuity without circuit modification.

Q: Are there any compliance differences between the substitute parts and the original?

A: Yes. The substitute parts P3602ABL and P3602ABLRP are ROHS3 compliant and REACH unaffected, whereas the original P3602ABRP is RoHS non-compliant. This represents an improvement in regulatory compliance for new designs or production runs.

Q: Can I mix P3602ABL and P3602ABLRP in the same assembly?

A: Yes. Since both parts are electrically and mechanically identical, they can be used together in the same circuit or assembly without any compatibility issues.
